OIL-CUP LUBRICATOR.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed February (b190 $9Ti81Nm 023- To all whom "it may concern:

Be it known that I, WILLIAM P. PHILLIPS, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Oil-Cup Lubricators, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to oil cup lubrica tors whereby oil or similar lubricating medium may be fed to the desired portions of mechanisms of various types.

WVhile the invention is particularly useful in connection with gas engines or explosive engines of various types, it is in certain of its features applicable to many other types of engines or mechanisms and may with regard to such features be of general application.

The invention more particularly relates to the provision of means whereby the valve and its related parts and. herein the main cover and filling cover may be held in proper position. i In order that the principles of the inven tion may be fully understood, I have shown a single type or embodiment of the invention in the accompanying drawing, wherein Figure 1 is a side elevation of a lubricator embodying my invention, the valve being seated; Fig. 2 is a vertical central section of the lubricator, upon an enlarged scale, the valve being lifted, from its seat; Fig. 3 is a side elevation of the valve and parts directly carried thereby; and Fig. 4 is a detail sectional view showing the main cover open.

Referring to the single type or embodiment of the invention disclosed in the accompanying drawing, the lubricator cup is indicated at 1, it preferably and as here shown 'being of transparent material.

The cup is adapted to be mounted in any suitable manner upon the mechanism to be lubricated, which may be a gas or explosive engine or other mechanism.

As here shown a valve seat 2 is formed upon the lower portion of a vertically dis posed valve casing 3 extending through the cup and the cover thereof, the lower end of the casing being preferably screw threaded to receive a fitting 4 whereby the lubricator may be secured to the mechanism to be lubricated, such fitting preferably having the usual or any desired sights.

Mounted Within the valve casing is a veragalnst the valve seat 2 and to extend 1on gitudinally of and beyond the upper end of the valve casing In the present form of the invention, a main cover 6 is provided which may have a flange concentric with and preferably surrounding the upper edge of the cup. Such cover is here shown as having an opening 7 therein, preferably concentric with and surl rounding the valve casing. Mounted upon such cover and of slightly larger diameter than the opening 7 is a supplemental or filling cover 8, preferably formed as a thin meta lie disk, such cover bein mounted' upon the valve casing and preferably so tightly fitting the same as to have little or no longitudinal movement thereon. If desired, and as indicated in Figs. 1 and 2, the supplemental cover may comprise an upper and a lower portion. The lower portion 8 may be nonmetallic and ti htly fit the valve casing, the upper portion being preferably metallic and resting thereon, and if desired loosely fitting the valve easing.

The valve 5 has loosely mounted thereon a cap or memer portion thereof which is preferably employed being here shown. as interiorly screw threaded to engage exterior threads upon the upper end of the valve casing. The valve 5 has lined thereon a collar 10 between which and I I tieally disposed valve 5 adapted to be seated l the inner face of the top of the cap 9 is dis posed a spiral spring 11. \Vhen the cap 9 is secured upon the upper edge of the valve casing, the tension of the spring 11 is thereby I increased, the valve being thus forced to its l seat and maintained there by such spring pressure. In order to lift the valve from its seat without unscrewing the cap 9, preferably a pivoted cam lever 12 is pivoted to the valve 5 at or near its upper end. heir the cam lever is turned into a horizontal position as indicated in Fig. 1, the valve is pressed to its seat by the spring 11, but when the lever is turned into an upright position as indicated in Figs. 2 and 3 the engagement of the foot of the lever 12 upon the upper face of the top of the cap 9 elevates the pivot of said lever, and hence lifts the valve from its seat. l In a lubricator valve as thus far described, when the valve is seated, that is, when the cam lever is removed from engagement with the upper face of the top of the cap 9, the cap 9 is maintained in its adjusted or correct position by means of the pressure of the 9, a depending cylindrical I spring 11 against the under face of the top of the cap 9, and the friction between such cap and the spring is sufiicient to prevent rotation of the cap excepting as considerable and intentional force is applied thereto and hence the parts are maintained in correct po sition. \Vhen, however, the valve is elevated from its seat by the described engagement of the cam lever 12 with the cap, then such lever, the valve 5 upon which it is mounted, the spring 11 and the cap 9 become as it were locked together and act as an entirety and hence there is nothing to prevent rotation of the cap 9 upon the screw threads at the upper edge of the valve casing for the friction between the cap and the spring 11 is neutralized by the engagement of the lever 12 and the cap. Thus the adjustment of the cap 9 may be accidentally changed.

Devices have heretofore been employed to engage with a cap or other part upon a valve to prevent rotation thereof, said devices sometimes assuming the form of a bowed spring clip, a portion whereof engages the roughened face of the cap.

In accordance with my invention, I employ a spring which holds the cap 9 from rotation whether the valve 5 be seated or not, and, in the present type of the invention, such spring performs the further function of holding the supplemental or filling cover in position and holding the main cover 6 in place. In the present type of the invention, such spring is indicated at 13, it being preferablya coil spring surrounding the valve casing and engaging at its lower end the up per face of the supplemental cover and at its upper end a portion of the cap 9 and herein its lower edge, thus exerting its tension against both of said parts and preventing rotation of the cap 9 upon the valve casing, whether the valve be seated or unseated.

In order to fill the lubricator cup, in the present type of the invention, the main cover 6 is slightly lifted at one portion of its edge, so that its flange is brought above the upper edge of the cup and then is slid laterally beneath the supplemental cover 8 until a portion of the concentric opening 7 in the main cover is exposed. After filling the cup, the main cover is returned by a reverse operation.

It will be observed that in the present type of the invention, the spring 13 performs the triple function of preventing rotation of the cap 9 and of holding the supplemental cover 8 and the main cover 6 in position.

Having thus described one type or embodiment of the invention, I desire it to be understood that although I have used specific terms, they are employed in a descriptive and generic sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
